A simplified circuit for an analog input is shown in
nected to a digital output, they have reverse biased diodes to V
therefore, must be between V
than 0.6V in either direction, one of the diodes is forward biased and a latch-up may occur. A
maximum source impedance of 10 k is recommended for the analog sources.
